| description | In order to enhance welding quality control, the present invention is characterized by comprising: a magnetic field measurement device (205) that is provided in the periphery of a weld during resistance welding and measures the local electric current in the weld; a high-speed camera (202) that captures an image of the light emission state in the weld, and captures an image to be used for measuringthe local temperature in the weld from unevenness in emission luminance; and a comparison/determination unit (106) that compares electric current information calculated on the basis of magnetic fieldinformation acquired from the magnetic field measurement device (205) with past electric current information, and compares temperature information measured from the image captured by the high-speed camera (202) with past temperature information so as to determine whether at least one of the electric current information and the temperature information has an abnormal value.
